Terrestrial Photogrammetric Reconstruction of Black Spruce (Picea mariana) Tree

This photogrammetric point cloud was constructed using a set of 12 spherical images taken at different heights at two locations around the tree.

The tree is a black spruce (Picea mariana), with a diameter at breast height of 20.7 cm. The tree is located within Forest Management Unit S20 near the towns of Slave Lake and Swan Hills in Alberta, Canada.

This research was funded by the AWARE (Assessment of Wood Attributes using Remote sEnsing) Natural Sciences and Engineering Research Council of Canada Collaborative Research and Development grant to a team led by Dr. Nicholas Coops with support from West Fraser and Alberta Agriculture and Forestry.

本数据集的摄影测量点云（photogrammetric point cloud）由围绕该树木的两个站位、不同高度下拍摄的12张球形影像构建而成。

该树木为黑云杉（Picea mariana），胸径达20.7厘米，生长于加拿大阿尔伯塔省斯莱夫莱克（Slave Lake）与斯旺希尔斯（Swan Hills）附近的S20森林经营单元（Forest Management Unit）范围内。

本研究由加拿大自然科学与工程研究理事会（Natural Sciences and Engineering Research Council of Canada）面向AWARE（Assessment of Wood Attributes using Remote Sensing）项目的合作研究与发展专项基金资助，该项目由Nicholas Coops博士领衔的团队主持，并获得West Fraser公司与阿尔伯塔省农业与林业局（Alberta Agriculture and Forestry）的支持。
